Performance of Seismically Isolated Pile-supported Structures through 1 g Shaking Table Tests
نویسندگان
چکیده
This study fabricated friction pendulum (FP) and rolling (RP) seismic isolation systems using 3D printing to conduct 1g shaking table tests of pile-supported structure models incorporating these systems. The test results indicate that, when the FP bearing was applied pile heads, acceleration response decreased once began operate; as input earthquake frequency increased (1, 3, 10 Hz), system engaged at lower accelerations (0.16, 0.11, 0.02 g, respectively), deck significantly (15, 37, 65%, respectively) compared that in fixed head condition. Similarly, RP a higher Hz) corresponded greater decrease (82, 95, 96%, However, significant displacement observed owing resonance phenomenon natural period similar earthquake. Therefore, since applying is not desirable terms structural displacement, it appropriate apply bearing, which can avoid by changing during operation system.

DEVELOPMENT OF RELATION FOR THE SEISMICALLY BASE ISOLATED STRUCTURES USING MODIFIED ABC ALGORITHM
In this paper, the effective parameters on the ductility demand of the seismically base isolated structure are investigated, and then a relation between the strength reduction factor and the target ductility is presented. The investigation has been conducted by modelling the base isolated structure as a two degree of freedom model in the OpenSees software, and the possibility of yielding in the...
متن کاملPerformance of High-Rate Kinematic GPS During Strong Shaking: Observations from Shake Table Tests and the 2010 Chile Earthquake
Over the last decade, the 1-sample-per-second kinematic Global Positioning System (GPS) has been used as a displacement sensor in earthquake observations and for structural health monitoring. Many researchers in both seismology and engineering have expressed the desire for higher-sample-rate (10-sample-per-second or higher) GPS data to acquire high-frequency displacement information. We perform...

متن کاملBidirectional Shaking Table Tests of a One-fourth Scale Reinforced Concrete Space Frame
Shaking table tests on the 1/4th-scale three-story reinforced concrete frames were carried out to investigate the effects of bidirectional earthquake motions on overall nonlinear response of reinforced concrete frame buildings. Two identical models were constructed and one was subjected to bidirectional horizontal earthquake motions and the other was subjected to unidirectional one. A series of...
